Hello all- We received our Preliminary Construction Review from USGBC for a LEED-NC 2009 project.

Hello, I am wondering if a hair washing sink/spray valve are considered process water and excluded from the Indoor Water Use Calculator, or if they should be included. Thanks!

Is it compulsory to follow all SMACNA guidelines to achieve this credit? or you can leave out a few and still earn the credit?

The CEN - EN 779 for air filter performance is currently inactive?

Why was Construction Indoor Air Quality Management Plan - Before occupancy changed to Indoor Air quality Assessment?

If we follow all the SMACA guidelines strictly, is it possible to earn the low VOC credit as well ?

What is the lag time for historical embodied carbon data catching up with real-time information as manufacturers source renewable energy?

Our project proposes a green wall to be planted with appropriate vegetation and climbers.

To earn the 3 points on this credit, Question 1: Do I need to know life cycle analysis for 100% of my structural and envelope products? Even small products like tightness, ...?

Hello everyone, 

Where can I find WELL CE courses? 

Thanks
